SignalBox

Camera control for podcast and video studios

Every camera in your studio. One remote.

SignalBox finds your Sony and Blackmagic cameras on the local network and puts recording, exposure and status for all of them on one panel — in a browser, on your phone, or docked in OBS.

The SignalBox control panel: two studio groups. The first holds four Sony cameras with record buttons, battery, card time, ISO, shutter, aperture, mic gain and white balance, one with Live Preview open and one showing an overheating warning. The second holds two Blackmagic PYXIS 6K cameras recording, with tally, recording time, format, ISO, shutter, gain, white balance and tint. The panel’s interface text is in Russian.

How it works

From install to REC in three steps

No capture cards, no extra cables. SignalBox talks to the cameras over the network you already have.

  1. Install it on one studio computer

    SignalBox runs quietly in the Windows notification area or the macOS menu bar. There’s no window to keep open — it starts, finds the cameras and serves the control panel.

  2. It finds your cameras

    Sony cameras on Wi‑Fi and Blackmagic cameras on Ethernet are discovered automatically. If your network blocks discovery, add a Sony camera by its IP address once (this works for the models listed in the panel, including every tested one) and SignalBox remembers it.

  3. Open the panel anywhere

    In any browser on the studio network, on a phone by scanning a QR code, or as a Custom Browser Dock inside OBS Studio. Everyone sees the same live state.

Features

Everything the operator needs, on one screen

Built in a working podcast studio, for the moment when four cameras have to start recording at once.

One-button group recording

Organise cameras into groups — one per set or room — and start or stop every camera in a group with a single REC. Drag cameras between groups and reorder them as you like.

Exposure from the panel

Sony: ISO, shutter, aperture, white balance in Kelvin and mic gain. Blackmagic: ISO, shutter, gain, white balance and tint. Set them per camera, or step ISO, aperture, shutter and white balance on all Sony cameras in a group at once. Value lists come from the camera itself, and the panel shows the value the camera reports; for ISO, shutter and aperture on Sony and for every Blackmagic control, SignalBox also checks that the change took effect and repeats it if it didn’t.

Live status at a glance

On Sony: battery, mains power and minutes left on the card. On Blackmagic: timecode, recording time, tally and power source, with an Offline mark when a camera stops responding. A Sony camera that drops off the network disappears from the panel until it reconnects.

Live Preview with focus frames

Open the camera’s live picture right in its card, with autofocus and face-detection frames, or switch it to full screen to check framing.

Sony cameras

Overheating warning

When a camera reports that it’s getting close to overheating, its whole card lights up with a warning — while there’s still time to do something about it.

Sony cameras

Hotkeys and MIDI

Assign a keyboard shortcut or a button on a MIDI controller to start and stop recording on a group. Shortcuts are registered system-wide, so they work while you’re in another app; on a Mac, pick one that macOS doesn’t already use. Connect the MIDI controller before you start SignalBox.

Cards the way you want them

Choose which controls each camera card shows and in what order. The layout is saved per camera brand on the studio computer, so every device that opens the panel sees the same cards.

Private, works offline

Everything runs on your local network. SignalBox doesn’t send us anything about you, your cameras or your footage; it goes online only to check for and download updates.

Updates built in

SignalBox checks for new versions and installs them when you say so — or automatically, if you turn that on. Installing an update restarts SignalBox, so you may want automatic updates off during shoots. Your cameras, groups and settings are kept.

One panel, three places

Open it wherever you work

The panel is a web page served by SignalBox on your studio computer, so any device on the same network can open it.

In the browser

On the studio computer or any laptop on the network. SignalBox opens the panel for you when it starts.

On your phone

Scan the QR code shown in the panel. On a narrow screen the cards line up in a single column.

Inside OBS Studio

Add the panel as a Custom Browser Dock and control the cameras without leaving your streaming or recording setup.

Cameras

Sony and Blackmagic, side by side

SignalBox isn’t tied to one brand. Each camera gets a card built from what its own interface really offers — no placeholder controls that do nothing.

Sony

Wi‑Fi · Camera Remote SDK

Cameras that support remote shooting from a computer over Wi‑Fi (“PC Remote”) through Sony’s Camera Remote SDK.

Control
Record, ISO, shutter speed (or shutter angle where the camera reports it), aperture, white balance and Kelvin, mic gain
Status
Battery, mains power, card time left, overheating
Picture
Live Preview with autofocus and face frames
Tested with
ZV-E1α7S IIIFX3AFX30

Blackmagic Design

Ethernet · REST API

Cameras with Blackmagic’s camera control REST API, found automatically on the network. Remote control (Web Media Manager) has to be switched on in the camera.

Control
Record, ISO, shutter, gain, white balance, tint
Status
Timecode, recording time, tally, recording format, power source
Picture
No live picture for Blackmagic cameras yet — use your monitor or switcher for that
Tested with
PYXIS 6K

Not on the list? Other Sony models that support PC Remote over Wi‑Fi in the Camera Remote SDK, and other Blackmagic cameras with the REST API, are expected to work, but we haven’t tested them ourselves. They have to be found automatically: adding a camera by IP address works only for the models listed in the panel. Try SignalBox with your camera — if it doesn’t work for you, our 30-day money-back guarantee has you covered.

FAQ

Questions, answered

What happens after I pay?

Paddle emails you a receipt, and you land on a page with download links for Windows and macOS and a short setup guide. Install SignalBox on a studio computer and it opens the control panel in your browser by itself.

How do I cancel?

Whenever you like: use the link in your Paddle receipt email, or “Manage subscription” at the bottom of this site. Cancelling stops future payments, and SignalBox stays yours to use until the end of the month you’ve already paid for. You can also simply write to us and we’ll cancel it for you.

Can I get my money back?

Yes. Ask within 30 days of any payment — the first one or a renewal — and you get that payment back in full, no questions asked. A refund also cancels your subscription, and your licence for the period that payment covered ends. The details are in our Refund Policy.

Who is Paddle, and why is it on my bank statement?

Paddle.com is our online reseller and Merchant of Record. It takes the payment, calculates and pays VAT or sales tax, issues your invoice, and handles refunds and billing questions. That’s why the charge on your card statement reads PADDLE.NET* SIGNALBOX (PayPal shows PAYPAL *PADDLE.NET). You can look up any Paddle charge at paddle.net.

Does SignalBox need an internet connection?

No. It works entirely on your local network, so a studio without internet keeps working. SignalBox only goes online to check for and download updates.

Can two computers control the same camera?

Sony cameras accept one controlling computer at a time. Run SignalBox on one computer per studio network — everyone else opens its panel from a browser or a phone, so the whole team still shares the same controls.

Is the interface available in English?

Not yet: the panel and its settings are in Russian. Camera values use standard notation (ISO, shutter, aperture, white balance, REC), so the controls are easy to read, but menus and messages are in Russian. If that doesn’t work for you, the 30-day money-back guarantee applies.

Why does my Mac ask me to confirm opening SignalBox?

SignalBox for macOS isn’t notarized by Apple yet, so the first time you open the installer, macOS blocks it: allow it in System Settings → Privacy & Security (“Open Anyway”). Recent macOS versions also ask whether SignalBox may access the local network — allow it, otherwise SignalBox can’t find the cameras. The setup guide after purchase walks you through both.

Is my footage safe?

SignalBox sends commands to the cameras — start, stop, settings — and never touches your recordings: they stay on the camera’s own card or drive. Wireless networks can drop commands, so for important shoots take a look at the camera itself to confirm it’s recording.

Can my company get an invoice?

Yes. Paddle issues an invoice for every payment. At checkout you can add your company name and, where it applies, a VAT or tax number.
